Pre 50s: ==Overt or indirect discrimination== on basis of race, ethnicity, national origin (selects immigrant on certain background aka whiteness)
==PC 1911-1324 : preferred barring African American immigrants== because « unsuitable to the climate and requirements of Canada »
==Reform==: 1960 ==Bill of rights=== applied to actions of the federal government (not for provinces) → cannot discriminate on basis of race, national origin, Colour, religion, sex…
Changing the basis of immigration → PC 1962-82 ==skills>race== + PC 1967-1616 ==Points system== (if you check n amount of boxes especially concerning economic skills)
After 1971= demographic in terms of national origin shifts (2011 mainly Asian, African and south-American immigration)
